FREDERICK C. BILLINGS, OF MACON MISSOURI.

DRAWER-GUIDE.

SPECIFICATION forming part of Letters Patent No. 768,927, dated August30, 1904.

Application filed January 15, 1904.

T0 all whmn it may concern.-

Be it known that I, FREDERICK O. BILLINGS, a citizen of the UnitedStates, residing at Macon, Macon county, State of Missouri, haveinvented certain new and useful Improvements in Drawer-Guides, of whichthe following is a specification containing a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to drawer-guides, my object being to construct anantifriction drawer-guide consisting of but two members so arranged thatthe drawer is supported and centralized, thereby avoiding friction atthe sides as well as at the bottom of the drawer; and my improveddrawer-guide comprises the combination, with a frame having adraweropening, of a drawer adapted to slide in said opening, thesupporting surfaces of said drawer being oppositely inclined at an angleof approximately forty-five degrees relative to a horizontal or verticalline, ball-races mounted in said opening, and balls in said ball-racesto sustain and guide said supporting-surfaces, so that the drawer issupported by said balls, and so that the drawer is held in a centralposition with its sides out of contact with the frame.

In the drawings, Figure 1 is a perspective of a table-top, showing onemember of my improved drawer-guide in position for use. Fig. 2 is anenlarged detail showing the frame-opening, the drawer in section, andthe drawer-guides in position for use, the frame being broken away toeconomize space. Fig. 3 is an enlarged detail of one member of thedrawer-guide. Fig. 4: is an enlarged sectional detail through the drawerand the drawerguide, the frame being broken away.

Referring to the drawings in detail, the frame 5 has a drawer-opening 6,and the drawer 7 is adapted to fit in this opening. The sides 8 of thedrawer extend below the bottom 9, and the lower edges of the sides 8 arebeveled oppositely to an angle of fortyfive degrees relative to avertical or horizontal line, and the bearing-plates 10 are placed inposition and secured to these beveled faces to form hardsupportingsurfaces for the with the frame.

drawer. The ball-races 11 are placed in the lower corners of thedrawer-opening 6 with the balls in contact with the supporting-surfaces10, so that the balls support the drawer and cause the drawer to assumea central position, so that the sides 8 are out of contact Inconstructing the ballraces I take a tube and cut away substantiallyone-third of the tube, fill the tube with balls 12, bend portions of thetube laterally to form the end walls 13, and leaving the ears 14extending beyond the end walls 13, through which screws or nails areinserted into the frame 5 to hold the ball-races in position in thecorners of the drawer-opening 6. After the ball-races have been placedin position the open sides are oppositely inclined tomatch theinclinations of the supporting-surfaces 10. In cross-section theball-race 11 is somewhat greater than a half-circle, so that the ballsmust be inserted from the end, and when so inserted and the ends closedthe balls will remain in the races. Thus I have produced a drawerguidecomprising two independent members which form an antifriction-supportfor the drawer and which serve to centralize the drawer, thus holdingnot only the bottom, but both of the sides of the drawer out of contactwith the frame.

I claim In a drawer-guide, the combination with a frame having adrawer-opening; of a drawer adapted to slide in said opening, thesupporting-surfaces of said drawer being oppositely inclined, ball-racesmounted in said opening and balls in said ball-races in position toengage said supporting-surfaces, each of said ball-races comprising apiece of tube one-third cut away in cross-section, end pieces closingsaid tube and holding said balls in position, and ears extending beyondsaid end pieces to secure the. ball-races to the frame, substantially asdescribed.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
